Abstract (en)

[origin: WO2015050840A1] An example method for making downhole measurements may include positioning a tool with a conformable sensor within a pipe in a borehole in a subterranean formation, and generating a first electromagnetic signal using at least one of a plurality of transmitters of the conformable sensor. A first response to the first electromagnetic signal may be measured using at least one of a plurality of receivers of the conformable sensor. At least one of a scale parameter, a pipe parameter, and a stand-off distance between the conformable sensor and the pipe may be determined using the first response.
